Synergy of two catalysts in one flask

Exploration of a new chemical synthesis process for medications


Most medications, agricultural chemicals and functional materials, indispensable for maintaining and improving our lives, are composed of organic molecules. Organic synthesis using a catalyst is the method for the rapid and large scale supply of such organic molecules without imposing a heavy ...

Photosynthetic microalgae as biocatalysts

The biocatalytic production of chemicals should become considerably more sustainable


A carpet of blue-green algae can literally ‘cloud’ the summer’s swimming pleasure at the lake. This is caused by a few strains of photosynthetically active microalgae, also known as cyanobacteria. Other harmless strains of cyanobacteria have great potential for biotechnological applications and ...

Nanostructuring increases efficiency of metal-free photocatalysts by factor eleven

Solar–to-hydrogen conversion


Polymeric carbon nitrides exhibit a catalytic effect in sunlight that can be used for the production of hydrogen from solar energy. However, the efficiency of these metal-free catalysts is extremely low. A team at the Tianjin University in China, in collaboration with a group at the ...

A protein that self-replicates


Long regarded as a biological aberration, amyloids are fibrous aggregates of short protein fragments. Amyloids have a bad reputation because they are thought to be the cause of multiple neurodegenerative diseases, including Alzheimer's, Parkinson's and Creutzfeldt-Jakob disease. It was only ...

Newly designed molecule binds nitrogen


Chemists from the University of Würzburg have developed a boron-based molecule capable of binding nitrogen without assistance from a transition metal. This might be the first step towards the energy-saving production of fertilisers. Whether wheat, millet or maize: They all need nitrogen to grow. ...

Breakthrough process for directly converting methane to methanol


The direct oxidation of methane--found in natural gas--into methanol at low temperatures has long been a holy grail. Now, researchers at Tufts have found a breakthrough way to accomplish the feat using a heterogeneous catalyst and cheap molecular oxygen, according to a paper published by a team ...

The key to chemical transformations


Chemist Xile Hu is the winner of the National Latsis Prize for 2017. Hu, a professor at the École Polytechnique Fédérale de Lausanne, was recognised for his outstanding scientific career and his original contributions to the fundamental understanding of catalysis. Catalysis is a field of ...

New nanomaterial can extract hydrogen fuel from seawater


It's possible to produce hydrogen to power fuel cells by extracting the gas from seawater, but the electricity required to do it makes the process costly. UCF researcher Yang Yang has come up with a new hybrid nanomaterial that harnesses solar energy and uses it to generate hydrogen from seawater ...

Scanning tunneling microscopy measurements identify active sites on catalysts


Chemistry live: Using a scanning tunneling microscope, researchers at the Technical University of Munich (TUM) were able for the very first time to witness in detail the activity of catalysts during an electro-chemical reaction. The measurements show how the surface structure of the catalysts ...

Reusable ruthenium-based catalyst could be a game-changer for the biomass industry


Known for their outstanding versatility, primary amines (derivatives of ammonia) are industrially important compounds used in the preparation of a wide range of dyes, detergents and medicines. Although many attempts have been made to improve their synthesis using catalysts containing nickel, ...
